Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed August 9, 1916. Serial No. 113,945.

To all whom t may concern Be it known that I, Pio'rn GIRA, a subject of the Emperor of Austria-Hungary, residing-at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vehicle-Brakes, of which the following is a specification.

This invention relates to certain new and useful improvements in vehicle brakes.

The primary object of the invention is the provision of a brake especially adapted for wagons and similar vehicles readilyV operable from the drivers seat whereby b earing members are frictionally contacted with the wheels of the vehicle and retained in position until manually released.

A still further object of the device is to provide a brake operating means actuated from a point centrally of the floor of the forward end of a vehicle whereby the brakes may be readily set whenv desired, manual releasing means being'positioned at opposite sides thereof for readily releasing the brakes by means of either foot of the driver.

ln the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a side elevation of a wagon partially broken away provided with the present device. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged top plan view of the floor plate of the mechanism casing. Fig. 4 is a view similar to Fig. 3 with the cover plate removed showing the brake releasing mechanism. Fig. 5 is a vertical transverse sectional view taken upon the line V--V 0f Fig. 3. Fig. G is a similar view taken upon the line Vl-V of Fig. 3, and, Fig. 7 is a vertical longitudinal sectional view taken upon line VII-VH of Fig. 3.

The present form of brake is applicable to any wheeled vehicle and is herein illustrated in connection with a wagon 10 having rear ground wheels 11 journaled upon the opposite yends of the rear axle 12 beneath the wagon box 13 while a drivers seat 14 is arranged at the forward end of the vehicle having a floor 15 and dash board 16.

A casing 17 adapted for the reception of a brake releasing mechanism hereinafter set forth is secured beneath the Hoor l5 centrally thereof being provided with a cover plate 18 provided with a transverse slot 19. The bottom 2O of the casing 17 is provided with a transverse depression 21 having a guide-way 22 therein adapted for the sliding reception of a block 23. A foot lever 24 is arranged upon a plate 25 slidably positioned over the slot 19 and attached to a connecting member 2G arranged within the casing 17 and secured to the block 23.

A bracket 27 is secured to the rear axle 12 having a lever 28 pivoted to its forward end, the low-er end of the said lever being pivotally connected by a link 29 witha cross rod 30 connecting together oppositely positioned dependingr brake levers 31 having bearing blocks 32 upon their lower free ends arranged adjacent the rear wheels 11. The upper ends of the levers 31 are attached to a. rock shaft 33 transversely journaled beneath the wagon box or body 13 by a frame 34.. The upper end of the lever 28 is pivotally attached to an operating rod 35 extending forwardly beneath the wagon body and having an upturned forward end or goose-neck 36 freely extending through a slot 37 in the dash board 1G with the free end of the rod pivotally attached to thel foot lever 24 as at 38. It will be understood that the driver positioned upon the seat 14 may readily apply the brakes 32 by imparting a forward impulse to the lever 24-by means of his foot. Oppositely positioned toothed jaws 39 are pivoted within the casing 17 as at 40 having connecting springs 41 and 42V adapted for resiliently engaging the toothed portions 43 of the inner faces of the said jaws against the connecting member 2G of the foot lever 24 whereby the said lever is maintained locked in its forward position with the brake set until the jaws '39 are released therefrom by the mechanism hereinafter set forth, a return spring 44 being attached between the rear end of the rod 35 and the wagon body, being arranged to return the brake mechanism to its normal position when so desired.

rlfhe teeth upon the jaws 39 are so inclined as to permit the connecting member 2G to move forwardly ratcheting thereover but preventing a rearward movement of the lever 24 until the jaws are released. Oppositely projecting releasing arms 44 are pivoted to the jaws 39 and to crank arms 45 of gears 46 journaled adjacent the opposite ends of the casing 17. Similar gears 47 are positioned inwardly of the gears 46 in constant mesh therewith, a foot lever 48 being provided upon the axle 49 of each of the said inner gears 47. A foot plate 50 is arranged upon the free end of each of the levers 48 having depending pins 5l slidably arranged in guide slots 52 in the top plate 18V of the casing, it being understood that the forward impulse imparted to either of the plates 50 revolves the gears 47 and 46, which by means of the cranks and arms 44 taken with a connector 53 arranged between the arm 44 and asimilar arm 54 of the oppositely-arranged inner gear 47 eects an outward releasing movement of the jaws 39 allowing the connecting member 26 to move rearwardly under the inuence of the aforementioned spring 44. A strong and etlicient wagon brake is thereby arranged whereby the brakes are readily set from the drivers seat and locked in their set positions until released by either of the foot plates conveniently arranged adjacent the opposite ends of the floor l5.

What l claim as new is:

l. A wagon brake construction compris. ing oppositely-positioned resiliently connected toothed jaws, brake setting means shiftably arranged between the said jaws longitudinally thereof in contact therewith, and retracting means for both of said jaws operable at points adjacent the opposite ends of the casino'.
